Why not both?

The trouble now it is that Spring Boot allows getting things up and running without having to know anything about what is underneath.

That is great, until you have to change the way it behaves.

> all the "complication" and "bloat", but then just end up with homegrown unmaintainable crap that does half of what the frameworks offer for significantly more effort.

I don't see how you deduct the conclusion of reinventing wheels is the only solution of overcomplex and far from ideal frameworks. But you can categorise this deduction also.

So many times I have had to deal with custom "frameworks". I've become jaded.

At least with Spring, you only have to learn it once.

Agree. I have seen same thing where many people maintain a home grown crap called kitchen and think they can do better job than getting ready meal from restaurant.

Developers should not be writing code. Period.

Stupidity and arrogance is ruling everywhere.
