It could be. It was added as rebels wanted to have an option to be more tactical. You can use it to mark areas for your gang mates. "Need pick up at flashing strobe". Or marking enemy positions. Toss it next to a building and tell your mates he is in the building next to strobe.
Problem is, it doesn't seem to last very long when I have used it to mark areas. Other people have said they flash for a long time but it stopped for me after a few minutes.
I'd say the main purpose was for awesome night time NVG rave parties.
The IR grenades are not meant for marking. Chem-lights and Smokes do that.
They are actually used for Laser Designation. Instead of using a Laser Designer (from any source), you can throw an IR Grenade. The Mobile Artillery (Slammer?), AQ-40 Greyhawks and GBU12 bombs (found on CAS and Greyhawks) will be able to lock on to them.
But I agree, during darkness, they do make a decent marker and/or raveparty
