What Cummings is proposing is creating his own team, loyal to him, to circumvent the Sir Humphrys in the Civil Service.
The Civil Service, for good and bad, acts as a check on what governments can do. On the one hand they try to make ministers think through their plans and stop disastrous ideas being implemented; on the other hand they make it really hard for any real change to occur in the country.
I can understand
Edie being cheered by removing that barrier to real change, but I'll go along with everyone else in being horrified by the idea that any brain fart Cummings or Johnson or Patel or Gove or Hancock has will forced through without anyone saying 'wait a minute, that won't work because...'
