I support this message.
Would be nice to leave behind something to stop a recap immediately after you leave, mines of course, but a turret you could leave around/at capture points.
Wouldn't be too OP if they weren't all that good, but like the author posted originally they shouldn't be very strong, only strong enough to kill someone outright if their head was full of air
When tactically capping a base offensively you would just have to keep in mind that some one may have left behind a few treats. Also, correct me if I'm wrong. Didn't the turrets go offline if the generator was down in the facilities SOI in PS1? I don't remember any fond memories of laying turrets offensively with much luck, and most of my engineer days were defending facilities rather then attacking.
Anyways to not have some measure of autoturret would be silly imo.
edit: o ya tl:dr
