That's actually one of the general issues with heatpumps - because they aren't literally lighting something on fire (or using resistive heating which just lights money on fire) they have smaller temperature deltas when designed properly as you mention. This leads to things like oversized air conditioners in hot places because people will cycle the AC creating a high peak demand and if it isn't 'blowing cold' they think it isn't working.

Heat pumps (assuming they can vary their output, which most new ones can) work much better to keep a constant temperature whether hot or cold and actually create a really nice indoor environment if a) designed or sized correctly and 2) have good thermostat placement. There's plenty of software, standards, and guides out there to hit both of those and then you just have to educate the users to set a temperature and then forget about it other than monthly filter cleaning. This is hard coming from 100% or 0% duty cycle systems like most fossil-fuel heat and old-style air conditioners so some think heat pumps are 'wimpy' and don't work. Placement is also part of that - you shouldn't be sitting in the output of the unit (which tend to be lower velocity than forced hot air etc) because the unit should be placed so it can cool the entire space.
