Completely forgot to add this.
When/if the multiple border options is going to be added i would like
to propose the following structure.

Right now there are a dozen border options like border-radius. Those
will need to change to allow multiple borders but i think it would be
best to go with border names. So for border-radius you would get this:

border-radius: <name>, <radius>

But since that will break every site that uses border radius it might
be best to, if no name is provided, apply the setting (radius in this
case) to all border properties for the element.
And with border names:

border: <name>, ...

This way it remains backwards compatible.

As for the forced transparant border that won't get overdrawn by for
example a box-shadow it might be handy to use the !important option
like so:
border: 1px solid transparent !important;

What are your thoughts on this?
