Thank you for your reply. As far as I can see from the responses, people didn't quite get what I was trying to say right (purely my fault, of course). Probably due to several factors: my tone, presentation of information, English is not my first language and so on. But these are all excuses and I admit it.

I would like to note in advance once again - I am not trying to offer any specific solution. The text is not written for marketing purposes. Also, I am not suggesting to throw away all modern technologies, as it may seem. I am not a fan of such revolutions :)

Current technologies, for the most part, offer a balanced solution to the problems faced by web developers. Yes, with its own peculiarities and limits, but nothing is perfect. And that's perfectly fine. Moreover, every such technology throughout the years has been literally necessary for the overall development of the sphere. And despite everything I have said, none of them can be thrown out or said to be useless.

Also, as some may have mistakenly noted, I'm not from the mobile development field, so I don't seem to be trying to pull approaches specifically from that field. Well, at least consciously.

In general my main message is that maybe to solve the problems at hand in web development we don't necessarily need technologies that bring their own syntaxes, transpilers, modified html and so on? I'm not suggesting that custom syntax is a bad thing.

All I'm saying is that maybe it's time to look beyond the introduction of unique snowflake-like technologies? And start using what our own platform offers us and develop its usability. Perhaps not in the form that was presented, but in some other form. But, at least for me, it looks potentially possible.

We've already hit enough bumps in the road with current solutions and I believe that smart engineers (not me, haha) will be able to offer us something better.
