Some pros and cons to it imo
Also, adding a new sought after item post season 9 is very different than adding one pre season 8
Pros would be you get stacking, easier stacking because of the nerfs, some nostalgia for some, takes even more pressure off surrounding pve . A lot of players are significantly more skilled now and will do some pve grinding these days which creates a bit more challenging and interesting player pvp content. This becomes more interesting when the new pvp content hits this month, it'll be interesting to see HG/FotD/new pvp content working together.
Cons would be it's not really that interesting to many that aren't in that fotd style, more hopping for targets, fotd stacking is terrible for servers, I can feel it every time it's happening.
Personally I'd prefer them being randomly spread around for interesting adventure scenarios but it is what it is, CoFs seem to have done pretty well the entire time they've been around so far. They have made so many improvements with risk/reward in the last year that my days of being critical about stuff like this are pretty much over.
The game went from pretty terrible risk reward to solid and sustainable risk reward balance with improved pvp through leaning into opt-in pvp scenarios. So I'm much more supportive of this decision now than I would have been in season 6/7.
