Maybe, but in terms of understanding the code and having total control over it, it means a lot.<p>(And I don&#x27;t buy the large teams can&#x27;t adopt a self-grown code in the first place. If they&#x27;re any good, they can. If they&#x27;re not, then even their React and Angular skills will be bad).<p>Besides you know all your business logic code? That will be custom too, anyway,and they&#x27;ll have to adopt it...
