ZDoom does actually behave more like Heretic than like the DOOM games by default (freelook, walking over things, decorations block attacks, for example), although naturally not in respect to stuff ZDoom changed by fixing bugs or as requirements to make changes for additional features.

More of a bug of course than a limitation but ZDoom does support this.
The only real difference is that static limitations generally affect map designing and performance bugs playing; either may affect both, but one is usually more relevant while mapping the other while playing. A player wanting the classic feel (or to record Heretic v1.3 demos) will require the gameplay related bugs.
Simply turn on the flag and you're off to the races... literally.
ZDoom can have wall running, but it behaves differently. In ZDoom it applies to various directions, while in the DOS engines it's limited to when you move along a N/S wall towards the north. I think ZDaemon has a "classic" setting for this, but ZDoom doesn't seem to have more than 1 option (on/off).
There isn't a single map in Heretic however where this bug comes into play.
I doubt that. At Heretic-n you might find demos exploiting this.
I'd have to read up on it again to remember properly but it's got something to do with sectors.
There are various sound related differences, including the "silent BFG" (which might not be as immediately useful as in DOOM, but it still alters sound, such as when landing on the floor and firing at the same time), you don't hear other players' item pick-up sounds, sound hearing gets cut off more in Doom and works differently in any 8th level, and monster hearing is subject to different factors (in this WAD monsters wake up too early in Boom and ZDoom).
320x240
No, 320x200.
I don't really see this as affecting the game experience at all.
What it affects is the sound output; both SFX sound and OPL music playback (ZDoom only emulates it). A "chocolate" port wouldn't obviously support DOS sound behavior, though. A heretic port would likely use FMOD, in fact, and not SDL because it wouldn't be under the GPL.
I would love it if somebody could fill in the blanks here.
I don't have time to make a list now, but there are many differences, and none of these are irrelevant to an engine in general, since users would precisely seek a pure engine for various different (sometimes unexpected) reasons; testing levels, getting a classic feel, recording demos, doing research, &c.
Personally, I'm not too concerned about having a true Heretic port, as I'm not as much a fan of the game as I am of the DOOM games, and I can run it on a DOS compatible system anyway. Besides, as time passes DOSBox only gets better at running the PC games.
