This is the primary usage.
Curl is a cross-platform multiprotocol command-line tool and library
which could be used in other products.
I believe a lot of test engineers used this tool for querying network
services and devices.
As for SNMP, some subset of GetRequest/SetRequest could be useful for
the same reasons.
And better not to rely on net-snmp dependency if possible (it never
has a goal to be cross-platform).

Not sure about server-side (from FAQ "cURL is the name of the project.
The name is a play on 'Client for URLs')

All admins are actively used SNMP in their monitoring suites.

P.S.
As a joke (don't take it seriously) I've replaced SNMP with FTP and
rephrase your statement.
"I'm pretty sure I will never install and use curl instead of (ncftp
or other integrated ftp client)"
