Even (uncommon) country TLD's too. I own a .vg domain which is a perfect match with the initials of my last name. My mails end up in spam quite often too, despite having set up SPF, DKIM, DMARC and all that stuff correctly. It's just not common so some security systems block it.
It's not just about being common, it's also about the share of abuse coming from such domains.
Or just incompetence, I had to lobby to get .org unblocked for mail at some CS faculty of a (not my) university, 20 years ago.
Usually not, just look at for example SpamHaus's top abusive TLDs. New TLDs dominate.
