Yes, they will still drop their ashcans exactly where you are.
It seems the mod does not change this (yet), only they find you better
Now they also throw charges farther away, but if you are inside of a certain distance there is no chance, and this is wrong because just of all that close the ASDIC would temporarily lose contact, so a sudden fast turn would save you, at least for that attack run. Even several destroyers would not use the hydrophones while charges were thrown for obvious reasons. ASDIC is another thing ...
As well the boat gives in a bit too early, every time there is a damage your hull will suffer, while in reality it would merely have been a ruptured pipe, or some blown fuses without damaging the pressure hull as such.
Certainly, they used wooden beams to support dents in the pressure hull if charges had gone off really close - but to have a "pressurehull-o-meter" in percent ?
Either the hull is cracked, or not. And you will sure know it ..
Also remember SH2, i enjoyed it for the graphics (for that time lol) and played the competely scripted "campaign" (15 missions ?) one time, and the single mission at the Azores and the refuel one several times. And then never again ..
SH3 was a quantum leap, but the same depth charge problem. And SH4. And SH5.
