I think that vast majority of us - ordinary people end here.
They will use their power and money to engineer children with traits nowhere to be found in nature.
Fast-forward a few generations - I bet they will push our gene-sets out.
If a migration of breaking changes seems like a lot of work for you then I suppose that rolling your own framework won't be any better.
With the framework, you have structure. It might not be the best structure to use, but you have one. React lasted really long and is still works today.
Going without framework works if:
- you have a really small project
- you are so advanced developer or have specific use-case that using a framework creates more burden than time saving
- you are creating something so valuable that reimplementing it yourself is worth it
I think that regular website will bleed via maintenance costs in the long-run if you don't use a framework. Instead of paved road with framework migration you would be fixing and debugging bugs in your framework/codebase.
I have seen that method in work in one of large corporate companies here. :)
A meaningless, but "important" "manager" tries to orchestrate a public meeting to show off your work to force you to make the deadline.
I have been too short there to evaluate whether it works or not.
