Python 2 was deprecated when Python 3 was released, but the timeline of transition was over 10+ years.
Django has deprecation timelines that last over 1.5 years.
In Enterprise, its often seen to have deprecation last 7 years.
During deprecation, only maintenance is performed. That is---security fixes.
The real difference between deprecation and "maintenance mode" is that the later is indefinite and implies continuation until profit-loss. AWSv2 isn't in maintenance mode, its deprecated. Eventually Amazon may stop offering it, and doesn't want you to start using it, but while its in operation that doesn't mean they won't close security holes in services that offer it.
(Submitted title was "Google deprecating Angular 1.x Material library and is just closing issues and PRs", which was wrongly editorialized, since the article apparently doesn't say they're 'deprecating' the library, and 'just' is just spin. Submitters: please don't rewrite titles to put your spin on a topic, especially not to gin up controversy. If a title is misleading or linkbait, it's ok to rewrite it (see the HN guidelines), but the new title needs to be accurate and neutral, and should preferably use representative language from the article itself.)
Not sure if that helps that much though.
How you feel about this probably depends on if you're a user or developer. If you're a developer you view the issue tracker as a TODO list. If you're literally never going to bother fixing an issue, its best to just close it and move on.
Users seem to view issue trackers as defect trackers and believe that bugs should stay open until they're fixed.

If active project are always supposed to be closing, then deprecated 1.x branches of projects should have an even higher bar for anything they keep around open.
When you:
* Move all of your developers / resources from Project A to Project B
* On the page for Project A you state "Project A development efforts are focused on bug fixes and minor improvements."
* THEN you go and close a bunch of valid even minor / easily fixed bugs (ex https://github.com/angular/material/issues/1659) and PRs stating "This issue is closed as part of our Project B efforts."
...it's my opinion that Project A is now deprecated, even if they don't expressly state that it is.
> You are correct that many valid issues/bugs have been closed without resolution.
> Our team simply does not have time to address all issues AND build Angular Material 2. (This is what we have consistently stated in our Forum posts).
> We welcome community leadership with Pull Requests. Often those PRs have side affects, their scope of changes is too large, and ultimately the risk is simply too great to merge.
> So we close/reject the PR... we do this to protect the existing user base. Pull Requests that have granular improvements and fixes are much easier to assess, test, and merge... and thus can be quickly merged.
> Pull Requests that are submitted referencing closed issues will then trigger us to reopen those issues; until the merge is complete.
> After Angular Material 2 has been released, we expect to continue to support and improve Angular Material 1 for many quarters.
> Both versions are important. Both are need to support the Angular 1 and Angular 2 developers
For me it's clear while the work on Material 1.x is not prioritized, it's not officially deprecated and PRs are still welcome if they are reasonable in size and impact.
