git pull , git push -> both are making sense

guix pull, but no guix push -> doesnt make sense as there is no relation 
between pull and other used commands. (thus i suggested to use known 
linked-terms like update,upgrade...etc)

I see, for example it can be made as upgrade command to always read 
configurations which are only intended for upgrading the system and if 
you want to use downgrade then it will read configurations only intended 
for downgrading the system. (either by using the same config.scm or each 
command point to separated config.scm like upgrade.scm and downgrade.scm...)

by this can run system-upgrade , system-downgrade or 
dist-upgrade/downgrade..etc

Maybe there are better solutions like better terms or technical 
solutions someone can come up with to make things better than the 
current situation.
