But thinking (methodology) forces us to have a need; a markup language
either supports that need or not.  Having PIs does not force anyone to
use them.

At www.apache.org, the first design coccon uses PIs, the second design
does not. The comments are interesting and useful for why, but they
also make the same mistake of saying that because they have moved to
a system complexity where PIs are not needed, therefore PIs are bad;
this is despite them using them in their first system.  So PIs, at
least,
provide an alternative from that many designers find natural.
