If the checklist is too long, yes.
But most in-flight tasks (that might benefit from one) are not long.
For example, the ILS config is:
1. HDG mode current
2. NAV/GPS switch to NAV
3. EHSI Course Pointer to runway inbound
4. Autopilot to APR
Personally I also set the airport as a DCT and put the GPS in the OBS mode, with the OBS bearing being the runway inbound (the bearing gets set automatically from the CP if done after step 1) and that monitors the approach laterally. Not great if it is a big multi-instrument-runway place (the DCT isn't going to point to quite the right place, perhaps) but a lot better than nothing.
