TTV's (and other explosives) during gang rounds

[SimianC]

As a practical question, how would we go about disabling toxins during gang rounds without making that a way for player to tell the round type early? Does it matter, since gangs tends to get called out within minutes of the round starting?

There was actually code in place that prevented gang members from assembling and detonating TTVs, back in November 2019.
It's worth mentioning that this change was reverted because it was deemed a knee-jerk reaction that didn't really fix much. Since TTVS were problematic in other game modes, it was decided that adjusting how explosions work (make them less likely to gib/delete items, having them require more time/effort, etc.) would be a better change in the long-term.
