Note that minlength="n" is equivalent to pattern=".{n}".  Not clear if it's common enough to really need special handling.

No, minlength="n" isn't equivalent too pattern=".{n}". @pattern should only be used for specific cases given that it removes all semantic.

In addition of passwords fields that require a minimum length (I guess that would be the primary use case), minlength could be used for field that require a specific length in association with maxlength (with maxlength and minlength having the same value).
