Look at it the other way. The system allows more of the run of the mill, day to day, appointments to be fulfilled quicker. It therefore provides slack in the system for those who need another way to access it, for more complex issues, or those requiring f2f. All the GP's locally allow phone ins if you cannot access e-consult
My mum's surgery does not. They use a system called Klinik which is switched on 8-4 on weekdays. You "have" to use it. They won't make appointments in person or over the phone.
I have filled it in a few times for her, and once she went into reception, mentioned the Equality Act and said the onus is on them to make reasonable adjustments, not her (they told her to get a friend to fill it out for her). They then filled it in for her, which is hardly efficient, either.
I would show her how to do it, but as it's switched off most of the time, I can't unless I am with her on a weekday.
Like phone apps for car parks, these systems break the law. They are fine as options, not fine when made compulsory.
