The reason the standard requires the keyword is that the WITH-name
scoping rules are different in the two cases. This means it is possible
to construct 100% valid queries that mean different things depending on
whether RECURSIVE is present or not. Admittedly, they'd be uncommon
corner cases, but the short answer is that an implementation that does
not require the keyword will fail to process some standard-conforming
queries in a standard-conforming way.
IOW, no, we are not going to change this.
