Red face Airbus 320 Honeywell H3 FMGC Standard

Can anyone offer any insight into the new Honeywell H3 FMGC standard now available on the 320? In particular, what is behind Airbus’s decision to prioritise the vertical path over selected speed when in a “latched on profile descent”?

15 years of pulling speed to comply with ATC speed requests and then possibly adding a bit of speed brake to maintain or regain the profile if slowing in DES mode, but now the aircraft is maintaining a “latched on profile descent” at the expense of the selected speed unless I muck about in the MCDU or select OP DES or VS, the latter two then requiring an adjustment to selected Altitude to comply with coded STAR constraints.

Someone should have said “If it ain’t broke, don’t fix it”.

Any real world experience managing this “not really selected speed” whilst “latched on profile”. How is it working for you?
