I thought about it, but:

[rhaas pgsql]$ git show --stat
88e66d193fbaf756b3cc9bf94cad116aacbb355b src/include/catalog/
[rhaas pgsql]$

The comments in catversion.h say this:

* The catalog version number is used to flag incompatible changes in
* the PostgreSQL system catalogs. Whenever anyone changes the format of
* a system catalog relation, or adds, deletes, or modifies standard
* catalog entries in such a way that an updated backend wouldn't work
* with an old database (or vice versa), the catalog version number
* should be changed.

This commit did none of those things.

I see your point, of course, I'm just explaining why I didn't do it.
