That's clearly not what I said or implied, but if we're going for hyperbolic arguments, then no, I don't agree with you wanting to merge everything in the DB into 1 release, for ease of maintenance.
But seriously -
How do we decide if we split one vinyl release, that has 10 different vinyl colours, into separate releases? If someone finds enough value in it to do it properly, then they do it. Otherwise they don't.
If a fluctuation in a print colouring is considered important enough to someone for them to add it to the database, with the appropriate information and hopefully scans, then that seems appropriate to me.
In @HibiscusKazeneko 's case in particular, if this re-press represents something of significance to her (eg collectors try to collect both, one is worth more etc), then why not, we often do this with limited edition vinyl re-presses, even if the content and packaging is pretty much exactly the same.
That's not to say that I think it automatically qualified/ requires a new release, that would be daft...
