I have zero real excuse for never having built the game from source.

I have played with the modding surface available in the quakeC files tho!

I was experimenting with a game design element where firing a weapon didnt decrement the ammo, but auto fired.

In other words, you always fired whatever you had out, removing the ammo hoarder behavior, but also makes you very cognizant about explosive barrels and where you point that rocket.
