Hm, do we really want committers do that at any frequency? I think that
concern makes sense for contributors, but I think it's reasonable to expect
the docs to be built before committing changes.
It might be relevant that the dependencies for INSTALL generation are
considerably smaller than for a full docs build. It needs xsltproc, xmllint
and pandoc. Not tiny, but still a lot less than the full docbook toolchain.
On a debian container with just enough stuff installed to get through
./configure --without-readline --without-zlib (to minimize things installed
from another source):
apt-get install -y xsltproc libxml2-utils pandoc
...
The following NEW packages will be installed:
libcmark-gfm-extensions0 libcmark-gfm0 libicu67 libxml2 libxml2-utils libxslt1.1 pandoc pandoc-data xsltproc
0 upgraded, 9 newly installed, 0 to remove and 0 not upgraded.
Need to get 28.8 MB of archives.
After this operation, 193 MB of additional disk space will be used.
Re committers, the biggest issue would presumably be working on windows :(. I
don't think the docs build is integrated into the msvc tooling right now.

Fair point, no idea how big that aspect is. I'd expect xsltproc to be halfway
OK in that regard, and it's certainly not changing much anymore. Pandoc, I
have no idea.

It would. I guess it'd still be better than the situation today, but...
