Earlier quoted context omitted.
Ignore stuff that was added to HTML, CSS, and JS for last 4-5 years. You'll still have a pretty solid? GUI platform, likely more capable and accessible than Qt or GTK or AWT. With the usual compiler / transpiler stack, you'll have a nice, fast-to-market, non-esoteric development environment. All without the need to ship 100MB binaries.
Sorry but requiring web devs to ignore the last 4~5 years of progress is just unacceptable. Not that that would fix the situation, there are still rendering inconsistencies between browsers when using stuff like margins floats and tables.
No it's not. "Web dev" is one of the things in my toolbox and I still clicked on this well-knowing it was likely not truly cross-platform and keeping up with bleeding-edge features.
Truth is all development is about tradeoffs and Electron is one heck of a blob to ship to users... in a lot of applications a lighter weight artifact may be desirable where the trade off of the last 4-5 years of browser advancements may be perfectly OK.
Is it unacceptable? Sure - if your application needs features out of the last 4-5 years of browser advancements... but that's not most applications. If you need a bleeding-edge solution that's truly cross-platform then Electron clearly still is your choice as you're just shipping around a fancied up Chromium.
