to clarify spirit:
there's two presets a bit like this.
the (new) vanilla preset attemps to be closer to the sw renderer (lego quake, square particles etc), disallows texture replacements, it blocks half the screen with the sbar, it enforces nq physics and thus lacks prediction too. its oldskool. its somewhat risky to use it on account of the fact that it actually disables features that mods might depend upon (custom particles, or textures that replace placeholder wads). its basically aimed at func_msgboard people.

the other (old) preset is the 'faithful' preset, which is more like glquake with round particles and linear filtering and stuff, it has the qw hud, no startup demos and feels more modern, and supports texture replacements.
the others either disable everything to focus purely on speed, or enable rtlights and other stuff in abundance.
while you could have tweaked your config to activate most of the things the vanilla preset sets, an explicit option makes it much easier to configure it that way, the square particles thing is much easier to achieve, and there were unfortunately bugfixes needed to get it working properly, so those things are new whether you consider them significant or not.
otherwise yes, link spam is spam regardless of the value of the links, at least when they don't actually say what the link is about.
