Feature request: support for "special values" for all utilities

[UltraCakeBakery]

It appears to be that "special values" (aka keywords) like inherit are considered "arbitrary values" for utility classes like rounded.
I use the inherit keyword quite often and would like to not have to wrap inherit in [] like: rounded-[inherit]. This goes for all utilities, not just rounded.

I use the Svelte and UnoCSS's mini + attributify preset. Svelte does not like []$@% characters in attribute names, so whenever I need an arbitrary value for a utility I have to use a class instead of an boolean attribute, like I in this snippet:

{ #each types as type }
	<div relative first:rounded-t last:rounded-b mb--1px>
		<input type="radio" name="type" id="type-{type}" value={type} absolute z-0 class="top-1/2 left-4 -translate-y-1/2 next:checked:border-$primary-color next:checked:z-1" />
		<label for="type-{type}" relative block p-3 pl-12 gap-3 border border-light-300 class="rounded-[inherit]">
			{type.replaceAll('-', ' ')}
		</label>
	</div>
{ /each }

I considered making an PR, but do not know where to start since every utility value is interpreted/handled differently. Maybe some more active contributors/maintainers can add this quicker than I can.
