In 5E, the stated goal is to make ability scores count more. If that's the case, then we are going to have a problem with con. The other 5 scores represent things you can actively do, but Con is completely passive. Let me lay out an example.
The group needs to get into the mayor's house. The plan is to go tomorrow night. However, they first need to work out a way past the locked door in the back. I can see an approach based on Str, Dex, Int, Wis or Chr. I don't see any way to apply Con to this situation.
It's a sacred cow, they want to include everything D&Dish in 5E, so they won't get rid of Con, but if they were willing to make a good change for the system, I would ditch Con and have only 5 stats, or find another physical stat that is more proactive, or combine Int and WIs into a single stat while ditching Con to preserve the physical/mental balance of stats.
