The "OSR" movement is almost exclusively D&D OE, D&D BX, and AD&D 1E, with some love for GW.I don't think the term is subjective. It's a category of games based on era -- Generation 1 RPGs like OD&D, Traveller, Gamma World, Tunnels and Trolls, etc...
Some one-off efforts have done AMSH, AD&D 2E, and TFT; the TFT effort was just big enough that SJG put a new non-OSR edition into the mix (It's closer to the original than the pseudo-clone Legends of the Ancient World.)
T&T has avoided the OSR movement largely by being still in print. Some of the OSR fans are also T&T fans.... but most of the OSR fans aren't T&T fans, and it's not that popular. And by in print, I mean, the rules are substantially the same as they were in the 1970s, and available both electronically and on dead trees.
Traveller was retrocloned in 1997 or so. Before the open game movement was popular, released under a GNU FDL license. 6 stat was all the impetus Marc Miller needed to get CT back into print. It wasn't until Mongoose pulled a stupid and tried to go to a more restrictive license in MGT2E that the Cepheus Engine actually got traction...
We don't see clones of Star Frontiers.
We don't see clones of James Bond.
We don't see clones of FASA STRPG.
We do, recently, see a pseudoclone of MERP.
We do see clones of WEG SW, but they were done by the new WEG after the end of the old WEG, having rights to the system but not eh setting. D6 Space, and Septimus. Likewise, d6 Indianna Jones was reworked into D6 Adventure. D6 Fantasy can be seen as a pseudoclone of d6 Hercules & Xena, but really doesn't feel like it.;
BRP's mechanics were retrocloned early.. GORE is a clone of CoC... but not much is made of that, and Chaosium is opening up to fan works...
RUneQuest is all about the setting, but is otherwise pretty stock BRP, and thanks to Mongoose, the mechanics are open source. But most of the fans don't use the OSR identity...
... Because OSR is associated with D&D derivatives. And a certain early strident and often toxic group of fans. And controversial designers like Jim Raggi, Adam K., RPG Pundit, and others.
