I've seen this happen on many occasions, one example being the posting I made
to this list a few months ago where an organisation had spent so much money
setting up a PKI that they then had to use it (even though it was totally
unnecesary for what they were doing) simply because it was there.

Been there, seen that.  You're well into layers 8 and 9 whenever anything
related to PKI is involved.  I think the fact that PKI is so strong at
enabling layers 8+9 is its great appeal to the inhabitants of said layers.
