nowhere in the history of language has “there should be such a thing” meant or even implied “making such a thing is easy”

I know its hyperbole but you can’t possible back that statement up.

if anything it implies the opposite.

It doesn’t, but i agree it didn’t really imply the difficulty was high either.

I wasn’t saying the reply was correct, i was stating the intended meaning (at least as i see it).

To answer to your original post, design platforms with version control exist.

Some use git under the hood, some don’t, most don’t require you to understand git to use them.

Hopefully that saves you some time as now you don’t have to build the platform from scratch.

Downsides for sure, but it does work.

So, benefit of the doubt time.

That’s some mental gymnastics in there but let’s see if we can get it.

So the reply isn’t actually suggesting you create the platform for designers, they are pointing out that there is a lot more to competent platform/software design than it seems, so try it yourself and find out.

If it turns out you do in fact have the answers, great, we now have the platform you described.

Chances are you’ll find out just how difficult it is to do what you are suggesting and realise that implying someone could “just” create a platform for designers isn’t particularly realistic.
