No but cheap compact practice & has been in the DCLG entry level guide for small premises since the outset.
Unless somewhere it would be prejudicial to safety such as healthcare, large public assembly, etc you can't really say no on Fire Safety Order Grounds - it's ABC rated and electrically safe and will snuff a smaller A rated fire fine and melt on the embers - it's the established deep seated stuff it may have problems with (but not to be confused with BC Powder which really was poor).
You know & I know that it may be jack of all trades but master of none and can cause terrible secondary damage, but that's for the user to worry about not the regulator.
Water based & CO2 extinguishers may be better, but the revision is intended to reduce the burden of measures for really small premises & that includes having loads of different extinguishers for specific risks.
I can understand their reasoning & wouldn't throw a fit about it (but would if the place ended up full of BC Powder extinguishers from Halfords - to avoid confusion BC Powder extinguishers should be limited to the 9 kilo Monnex & Purple K units in specialist industry these days)
