As a former DM Of a GMOD Deathrun/Jailbreak community, I definitely think that bhop is a super-fun skill based mechanic that makes deathrun a lot more captivating and interesting instead of a slow and somewhat sluggish gamemode.
As much as people say it will ruin the game and make the runners severely overpowered and be able to skip traps, I will definitely disagree with this as I have a lot of experience in the gamemode and it is actually a lot harder since we will likely use manual bhop, comparative to GMOD that uses autobhop (though I am not certain whether the suggested bhop mod is auto or manual), and then even then groups of people skipping traps rarely ever even happens at all.
It is 100% worth a shot and does not break the game. Garry's Mod deathrun is very similar to TF2 deathrun and is evident of this! I would not mind giving it a trial first before we put the plugin on the server/don't put the plugin on to see what the community thinks with the plugin in action instead of just hypothetically! ^^
