Might be, but I'd rather have people required to fill in a version as bug reports for the source are useless withouth version number. So, there is no harm if people fill in a version for above categories, but it's a problem if they don't fill in one for php source bugs.
We should prob "overrider" the website, systems, etc. with "Irrelevant" for the version number?
It is not a storage problem, but a user experience problem. If users are forced to select version numbers, they will get confused. This is why the irrelevant version was introduced... I was also tempted to say it is a good choice, and envisioned the time when it will be removed, but now I see it might be better to keep it. Since I don't have experience with internals bug reports, I might be totally wrong, and the versionless bug reports might really be too annoying.
