Whether this now all changes now that they no longer have an interest in Blink (as was), and Wijet order new jets (if they actually have), we will have to wait and see.
Not forgetting there are other businesses based on the field, including Aerobility, who are a high-profile aviation charity and have recently been expanding their facilities.
As an aside which jets can operate legally out of there?
I can't speak with authority re. Public Transport Ops (I'm just a former puddle-jumper pilot who used to fly from the field), but I've seen biz-jet types up to Da900 and 7X.
There's a fairly regular Da2000 currently.
Jetairfly come with PC12's (as do others) on an occasional basis, as do Netjets with some of their smaller types (I've seen Excels and 125's).
