<div>@Nyall, that proposal appears to be specific to plugins --

<div>@Greg: I found that many of the exact dependencies were not
even available through the main channels. So if the QGIS devs
compile/build against such versions, I'm not sure there's an
easy way to even specify such a conda recipe, unless all those
dependencies are also made available somehow. I didn't expect
that those versions would not even be there with the others
for the various libraries. Could this imply that the library
developers don't want those versions to be used? Not sure.<br>

<div>As a user and developer, I just want to be sure that if I
pull down conda-forge qgis version X that I will get the same
effective distribution as contained in downloadable installer
version X. Right now, we are getting a very different set of
dependencies.</div>

Not really about the details of using conda but about the
concept:<br>
<br>
conda's documentation says it runs on "Windows, macOS and
Linux" but<br>
qgis also runs on at least NetBSD and almost certainly other
BSDs.<br>
<br>
it seems that to build something, including qgis the
requirement is<br>
that the things it depends on are present in some way that
is found by<br>
the build. People can choose to do that however they want,
and it<br>
seems funny to me to impose a requirement. If this is
really "let's<br>
publish a conda config file so that people who want to do
that can do<br>
less work", that's of course fine, but if it's more "if you
don't have<br>
conda then you can't build qgis", that's something else.<br>
