too strict "warn for possible use of component without uppercase tag name (#5302)"

[burningTyger]

Describe the bug
PR #5302 is too strict and will warn on any import that bears an html element name

To Reproduce

<script>
	import {b} from './some.js'
</script>

<b>Hello {b}!</b>

https://svelte.dev/repl/e29cafcb75874c8082a849ffbdd65dc1?version=3.29.4

It should only warn on real components.

What would you suggest changing the heuristics to? Keep in mind that we cannot tell what's in the imported file.

Seeing the warning in my app I opened the PR I assuming there was an array of "valid" elements (such as listed here: https://developer.mozilla.org/en-US/docs/Web/HTML/Element) but it only checks elements against imported names. No problem with that. It just causes the issued behaviour. Would it be a good idea to create such a list of valid elements? Or check against such a list as well to filter out false positives? The downside would be that it is basically an evergrowing list and it would add rather unncecessary weight to the compiler (since the checks against that list would only be for positives).

I have no issue with closing this if it doesn't affect anybody else.

I import time from store (as in example https://svelte.dev/examples#readable-stores), put it in <time> tag, and got this warning. Of course I can use other tag of variable name, but it would be nice to mute this, maybe something like this:

<time ignore:component-name-lowercase>{time}</time>

@ziggi You can use comments to ignore the warning: https://svelte.dev/docs#Comments

In this case you want to use:

<!-- svelte-ignore component-name-lowercase -->
<time>{time}</time>

@hmt oh, thanks.
