HTTP's semantics are meant to be layered on top of this way.. hence why
POST is used to send emails, complete transactions, upload images, etc.

HTTP's semantics are generalised so that intermediaries on the network can
have an understanding of what is going on with an interaction (in network
terms) but without having to understand the actual semantics of the
application that is driving the interaction. Provided the specific
semantics of your application don't conflict with HTTP's constraints,
there's no issue.
