No they do not have 8 card club often. In fact they VERY rarely have 8 card clubs. Not that they would open something else but it is really rare to hold an 8 card suit to start with.
KQJTxxx and out is more than enough for anyone to open 3
♣. You can add
♦K or KJ next to it. You can add
♦K and
♠Q or even
♦ KQ next to it and make it a REALLY sound 3
♣ opening if you like.

Most of these hands are way too strong for a preempt, so just because the hand is not a 3
♣ opener given by OP does not make 3 NT any better. It is just bad to go -200 -300 or -400 undoubled when +110 or +130 was available. Especially when the defense is alarmed by the fact that we are bidding 3 NT on a long running suit.
One of the beauties of preempts is to steal a very good partscore from opponents when both sides are making a partscore. But most people bid games with this type of hands and ruins it.
