So there are a lot of tickets that are trivial, or a bullshit job, or just really not fun but still need to get done and a manager/architect is perfectly capable of doing any of these. They SHOULD NOT be doing the big/hard/risky ones because that's not their job; they'll block the team or worse, steal the most rewarding work from those who deserve it. Senior non-ICs and BS tasks are a match made in heaven (for many reasons!)

But do you think they would work on those "trivial tickets" :-)

Idk. I've slung about 2M lines of C over the years, and it doesn't take much time to get back into it...
