think we see a lot of unbundling happening right now (I work on https://sst.dev/ so see a lot of different setups)

a lot of times these specialized services can really nail a more narrowly scoped feature set to the point where it's worth having stuff running outside of your primary cloud

it always depends, for me personally that bar is very high because like you said, now you have to copy paste secrets into yet another service among other things

some services are so good, like planetscale, especially compared to the cloud option that I'm willing to do that
