the 202405 feature freeze.

Yea, go ahead, lets stick to the PCD approach, given that Ard seems to
not have objections to that ;)


Apologies for my late response.

As I have mentioned before (I think?) I strongly prefer HOBs over
dynamic PCDs for values that are determined during PEI and not updated
later.

For other cases, I actually prefer protocols over PCDs because you can
depex on protocols, and not on PCDs so you never know if the dispatch
order is correct, i.e., whether PCD producers are dispatched before
PCD consumers.
