And it seems to me that regular vehicle spawnkillers (the ones that, for example, camp at the core just to damage vecs, or the one screenshotted in the thread on the Omni server that you linked) are quite rare here, these days.
But, when it happens in a game (even if it's rare), it really sucks. It's one of these things that makes people complain in the chat, and that can (or can contribute to) ruin a good game.
I do believe that spawnkilling vehicles is pretty much ok (you spend some game time when you could have killed people or attack nodes, to destroy enemy vehicles, that will eventually respawn, just like the people. Also, in some maps is pretty much mandatory to spawnkill some vecs as soon as possible).
What I think that it's not ok, is spawn "burning" them. Because they will stay burned (without respawning).
Also, if I read it correctly, the thread that you linked only takes into account the option of "shielded vehicles VS non-shielded vehicles", that would prevent vec full spawnkilling in every possibile case. With the regenerating locked vehicles (my point 2 of the first post, or 2+4 with Wormbo's input) you can still spawnkill, but not spawn "burn" (or at least, you can do it, but it will become tactically useless, unless these vehicles are needed for the enemy team in a short time, and in this case I suppose that it might be quite legit to just damage them, as for the Bitchslap/Tyrant/TripleSlap cases).
The game devs implemented the full shielding of the locked vehicles, that is very different from this one.
Also, we all know that there are some things in the ONS game mode that are not so well designed, and that exists since day 0*, and I believe that this might be one of these things.
I would like to talk with you about your mentality of "people solutions to people problems, tech solutions to bugs", but I know that it will quickly become a matter of philosophy, and that would go way beyond the topic of this thread... So I'm keeping this talk for another time

And finally, about the whole vec spawnkilling thing being "good" or "bad"... What if we open a poll about it?
If the community votes positive for a tech solution on this, would the vote be taken into account?
*(you often mention the fact that the classic scorpion is a deathtrap, and I TOTALLY agree - the EONS scorpion or the UT3 scorpion are way more fun and balanced for me; also, after these years, we all learned that chockepoints are not so fun - and looking at the stock maps, it seems that the devs didn't).
