BL3 and the Grenade Damage Bonus on Weapons?

Many guns in BL 2 had this nice little extra that took them over the top…

Unkempt Harold
Most Torgue Explosive weapons
Even the Hail had it.

Does this added bonus exist on weapons in BL 3?

Does having a Mod with +31% Grenade Damage help any weapons in BL 3?

Explosive weapons are so odd n BL 3.

Not even considered a real class of weapons…They are “kinda” elemental but not really.

If the new “Boomer” got both Splash and Grenade Damage bonuses…it might be exceptional on Moze. I already know it gets splash.
