pip installing motor do not installs dnsutils automatically nor does it support extra requirement as pymongo[srv] does. This creates conflict between pymongo4.0.1(latest) and pymongo<4(motor requires). also when running motor programs it ask to install pymongo with command "pip install pymongo[srv]" which again gives issue as it tries to install latest pymongo which is not support by motor yet.
This issue is annoying as everytime we install motor, we have remember to reinstall pymongo[srv] after installation. A possible solution could be to let user specify extra dependecies at the installation time.
