I see that we have a http-status-code-403 tag. It is quite clear what 403 is referring to in that tag name.
We do not have a http-status-code-500 tag. Instead we have 500 and 500-error, which are both very unclear names. All the questions I saw in those tags so far were about HTTP status code 500.
Any reason not to merge both of those tags into a new http-status-code-500 tag?
(As far as I can tell it requires a moderator to actually do it.)
