I've never seen a Xamarin app running on the browser, is that a thing? As far as I'm concerned the web is the most important platform I care about, if a framework doesn't support it at all, like perhaps the language used isn't even compatible with the browser, then I'm not personally interested in it.

I think that's why a lot of people are hoping for strong Blazor/MAUI alignment. I wish I liked Blazor better myself but I don't, it reminds me too much of the bad parts of ASP Classic wearing the skin of ASP.NET. Seeing the turduckens some of the hopeful are building of Blazor Razor Pages hosted in MAUI are interesting for sure, but partly in that way that I'm expecting a horror jump scare to follow.

(ETA: Sorry, that sounds way harsher than I intended. Waiting for coffee to kick in.)
