make
make install
...or the closest equivalent (e.g. some use meson or cmake).But to your point, there are a lot of projects for which those steps work just fine.
For example many early 2000s games that used SDL 1.x can be made to work on modern Linux simply by removing the SDL so file they were bundled with and let them use the one the system provides (most common issue would be audio but also mode setting or full screen support).
This isn't a thing only on Linux btw, SDL games that have an old DLL can also have issues on Windows (in fact a game of mine was like that :-P) but be made to work by simply replacing the DLL with a newer one.
1. Kubernetes
2. git-annex
3. The new generation of replacements for various core command tools (e.g. ripgrep, fd, etc.)
EDIT:
> several weeks of time
Out of curiosity, what projects were those that took several weeks? My presumption is probably very GUI heavy ones?
Debezium is also very Byzantine, or maybe it’s just that I don’t understand maven.

There's a little more to it (deb-src into /etc/apt/sources.list), but it's super-instructive to do it on something like 'busybox' and be able to make legitimate changes to something like 'ls' ... or do it to 'coreutils' and make modifications to the "real ls".
Although the "speed-bump" to being able to build packages for the first time is a bit rough, the benefit is that the documentation is outstanding and the process is pretty seamless for most/all packages, regardless of complexity.
The docs and tools are written by engineers and maintainers for people just like you... an independent consumer/programmer, sitting at their computer, trying to (re-) build a package to add a feature or fix a bug.
The other benefit is that the process is relatively consistent across literally thousands of packages and there's a lot of docs + tools +features to handle almost any scenario that Debian (Ubuntu) supports. If you learn it for one use case, your investment pays dividends across all other packaged software.
