I agree, and unless someone has a better reason than the ones I have seen, (saving tiny amount of bytes, less keystrokes, dx) I am convinced it's a bad idea to omit the end tags.

It causes way more trouble than those benefits are worth

I use an aggressively minnimal set of (valid) HTML because I prefer to write in HTML rather than Markdown-flavour-x.

Omitting the closing tags where possible is less about saving keystrokes than minnimising interruptions to my writing flow.

But I wouldn't advocate it for published documents, just my local scribblings.
