Yes, I didn't give much reason for not using a PI.

One important reason is that namespaces don't apply to PIs.
Dave gave another: the DOM doesn't give access to them.

Good practice: Namespace adoption

A specification that establishes an XML vocabulary SHOULD place all
element names and global attribute names in a namespace

I'm not aware of a list, just the one note about PIs:

"The use of XML processing instructions in this specification should not
be taken as a precedent. The W3C does not anticipate recommending the
use of processing instructions in any future specification."
