Are you guys repairing your lath plaster walls with drywall?

Hi there! I just recently bought a 1930 tutor house. A majority of the walls are lath plaster. I'm having an electrician come by to replace some electricals (I'm a little afraid of the knob and tube) so he's going to be making several holes in the plaster

Do most people patch their plaster walls with dryall and just try and make it look as close as possible? Or should I try and find someone who specializes in plaster to preserve the walls as best as possible? I'm worried that I'll be destroying my 100 year old walls and I'm very anxious about all this so any advice would be great. Thanks in advance
