I can not talk for the old or for the new Poser team and this "masterbug" is NOT a masterbug for everybody.

The end users that buy, load, pose and render content will never see this bug. So what is the issue? These users don't care and continue their creative art with outstanding results anyway.

This is a masterbug for content creators that want to deliver quality items and maintain optimal obj file quality and flexibility.

In the early days, Poser was created as a "pose" help. To get visualisation reference poses for artists that draw or paint people.

The setup room to actually "rig" obj files only came to the general public with Poser4Pro.

At the time many "hobby" content creators became vendors. And clothing became rigged and posable. Only when digging deeper into the possibilities of adding morphs, JCM's and all the rest we have now, did the double vertex issue surface. it is like a "handbrake" over what was/is possible with a properly vertex grouped and welded obj file.

So? it was, and still is, only a "masterbug" for content creators. (And most of them know their way around it by now.)

So, from being an "unkown" bug, it became a known bug, to a very important bug, to the "masterbug", to a less important bug because the workaround is out.

Load-pose-render users don't have a bug because they never run into the issue. Content creators that know their Job also knwo how to do the repair.

Hobby end users alsways have my Video4 on my youtube channel.

But having the bug is a PIA and requires the correct procedures to get around it.

See? LOL, Bugs are living things. LOL.
