It is by no means a normal scenario and i think you should give a tough fight for getting this setup in your company. It has far reaching benefits and has no point in realizing the same when you approach doomsday and it ain't the situation which fall under If it ain't broken don't fix it
Any reason for not implementing it could be only an excuse for bad work or a blunder waiting to happen.
Just tell them how great its to find what the app was on 1 Jan this year
how about hey this functionality was added in March i think we need to expand a bit more on this.
Wow this bug 154256 has been fixed in this commit.
i can branch out the app and send out the deployment no problem guys you can carry on working.
This can go on and on ... (remember to add comments on commits later on else that would be coming in as another question )
