Stiffen up tongue-and-groove floor with wood glue?

[Dr Benz]

Hello.
I'm wondering if you can get a more homogeneous floor by pouring glue into the grooves of the tongue and groove subfloor, thereby making it lock together more firmly?
Or is this unnecessary for some reason, or could it even impair the floor's functionality?

The idea is to lay floor gypsum on top (in a hall) so it probably can't be too stiff, right?

The tongue and groove are 45x19 if I remember correctly and are on joists CC 450.

Hilfe Bitte!

What is the purpose?

Completely pointless. You're supposed to apply drywall.

To get a more homogeneous subfloor under the gypsum. But it already feels quite stiff so maybe that's enough.

The plan is floor gypsum and then tiles on top.

Completely pointless. You're supposed to apply plasterboard.

Ok, so just gluing the plasterboards will be enough for it to be fine then.

Yes.
