The part about "doing everything" for someone hit home at first, but it took a turn when you mentioned leaving that position. Sometimes I've had managers come in and just take over a project because a client/investor wanted it yesterday, which I think is a bad approach. Sometimes it's necessary, but it should be mitigated by proper project management practices.

So it seems like a really strange assumption on your part that the new manager or the person "on track to be a senior dev" would behave in the way you expected. What exactly should a manager do different in that scenario? Close their "poop umbrella" and potentially let the person you're mentoring fail?

Furthermore, is shielding an employee with a "poop umbrella" tantamount to "doing everything" for them? I feel like putting your employees on track to a promotion and shielding them from organizational concerns that might distract them is a fundamental aspect of being a manager, if the next manager comes in and doesn't do that, then that's on them...
