The "one-person framework" thing is a big draw. I'm amazed at how productive I was in it, and it's not just at the code level. Even though I've been doing sysadmin/devops/architect work for over 25 years now, it's just so damn nice now not to have to think about e.g. standing up a HA PostgreSQL cluster or Redis and deployment is largely a solved problem.
There are two types of devs: those that ship and those that fill out surveys (and not because their stacks are so much more efficient that they have time to fill out the surveys)
Not many frameworks have been thriving that long, and there's good reason.
It packs everything, is tidy and productive, with a pleasant language to read and write.
In the latest Stackoverflow survey, it's back at the "top 5 of desired stacks to use for next project" over a decade after its inception !
Give it a try.
