You overestimate knowledge retention.

At one point there is a new hire who instead of learning why and how stuff was done starts overdoing everything because "previous people were shitty developers".

You will have easier time hiring people with standard stack as well, no one wants to work on hodgepodge of code where some dev 2 years ago did something and left never to be found again. Developers don't want to invest in some magic stack because it will be easier for them to switch jobs if they keep doing Angular/React.

If someone would be claiming he was building web apps without frameworks I assume he was not working in teams or at least not in teams of big companies. Which would be a red flag for me.

i don’t think building your own framework is a good idea. react still has plenty of possible patterns to decide between even after making the decision to use it. a team should have decided upon ways to do stuff even inside of a framework/technology/language.
