Yes, a bit better I think. More "self explanatory"... kind of :)

nothing forbids this although we may not have any use case for now...

A single TA is represented via a single device represented via UUID on
the TEE bus. And I can't think of a scenario where the user may not
want to split the TA so as to support a particular driver in Linux.
