Hi Rob,
Is it worth reserving space for a future Git or Github-cli style
plugin mechanism where third party tools can extend the `gdal` CLI?
eg: `gdal raster from-contours`
* `git foo` simply looks for internal code first, then executes
`git-foo` if it's present, then expands any configured command
aliases
* Github cli has an explicit extension install/packaging mechanism:
https://docs.github.com/en/github-cli/github-cli/creating-github-cli-extensions
I would let that aside for now (trying to limit as much as possible
the scope of the current RFC to avoid it going out of control). That's
something that should be relatively easy to add if someone needed
that. But actually you can already extend the "gdal" utility, for
commands a the top level, if you provide a shared library in the
gdalplugins directory and that it registers an algorithm the same way
built-in algorithms do. The bonus point doing that way is that
potential GUI built on top of gdal that would use "gdal --json-usage"
(or the equivalent C/C++ API) would autodiscover such extension with
its supported options.
Implemented per https://github.com/OSGeo/gdal/pull/12126
