On the other hand I have used Quarkus which was great until it wasn’t because a certain http feature wasn’t supported or we needed integration with an unsupported database. In enterprise that is enough reason to just choose for the batteries included option and lift along on improvements of the main framework.
How difficult is/was it to add a custom integration?
At this point the work is typically more than you want a single team to maintain. Unfortunately, in many large enterprises it is just easier and more efficient to grab a bigger framework than trying to organise sharing the custom integration in the organisation.
I'm back on Spring for work reasons but use it for all my side-projects.
