Yes & yes.

From what I've read or been texted, originally there were no explicit restrictions upon ship size.
CT Adv4 had the 'Leviathan' exploration vessel equipped with J-torps &, I've been informed, MM, himself, even refereed some sessions of that adventure, which I believe was the first official (GDW) one to be authored by an 'outside' source.

But it wasn't too much later that the explicit 100dt size plus pilot required rules appeared.

So, instead of a J-torp you'd have to carry 100dt jump-only capsules w/ a person inside, which is the same as....
(but you *could* make it J6, which , according to the TNS, the 3I intended to do to at least some of it's Xboats just before the 5th Frontier War broke out)

 Because  Marc says so. No other reason given, AFAIK.
And apparently J-Torps have been a major controversy.

 I'm
 curious. Exactly why can't Jump drives be
 miniaturised?
 And, if they
 can be, to what scale?
 The reason is,
 it would be an automated procedure to release a message pod
 with a miniature Jump drive that would replicate in reverse
 the Jump the ship just made, i.e. returning to the
 ship's point-of-origin to transmit "All OK"
 Failure for
 such a pod to materialise would sound alarm immediatelly.
