Sure, one could do that. But is it really worth the effort? I think not. I maintain that all effort would be better expended on trying to create a replacement system entirely from scratch. (well, not entirely. it should be built with modern, open-source software.)

My experience tells me that throwing everything away and starting again can look like the easy way forward. You get to discard all those mistakes! But it's not just my experience that says it's a huge mistake: https://www.joelonsoftware.com/2000/04/06/things-you-should-never-do-part-i/. Or perhaps you prefer a non-technical, parable version: https://www.goodreads.com/quotes/784709-suppose-that-a-great-commotion-arises-in-the-street-about.

> But is it really worth the effort?

I think so, yes!

And I wouldn't try to implement a "modern" perl backend but start with an attractive JS frontend.

Most importantly I would be capable to do a POC without messing around with the local patch system.

YMMV. (Certainly)

Can you elaborate on that?
