Aside from it being the full-time job of one person and breaking things for users about every release, it results in being yelled at by distribution people who don't like that the packages do not follow all the various and conflicting policies for each distribution, which results in them claiming the packages are low quality. Which might or might not be true depending on your pov but in any case it isn't work which results in many grateful emails about how nice it is that there are packages.
Now customers might need packages for RHEL or something and we will have to provide those but on the community side I and the others strongly prefer to rely on volunteers. This isn't company policy or anything, note, it is just how most of the employees think about it and as we're a company that works bottom up rather than having management meetings, this is pretty much the current state of affairs
If you or others have a good reason to not hire somebody for coding or sales but, instead, for packaging - I'm all ears and I am sure so are the others. But it will have to be somebody with a very thick skin, willingness to package for a wide variety of distributions AND be darn good at it so it doesn't break or change every 2nd release.
