I'd say a good engineer would do the math of "get my own space from
AFRINIC" vs "pay for more IPs from the provider". A very important point is
that moment when the contract is being negotiated - engineers should give
input in to this. I'd say two important points need to be made:

a) The institutions is paying for a circuit and transit
b) The institution should connect via BGP if they so wish do

This should counter that default position from some providers where a
connection means a CPE with a /28 and a NAT configuration.

Use the power of community to name and shame. I'm sure your institution is
not the only one at the receiving end of such policy,  when multiple client
 institutions collectively demanded the proper thing am sure they'll take
notice.  If the university is part of the BWC in Nigeria, that is a good
platform.

I've also seen a REN try to stop its member university from having and
advertising their own space. Fortunately, I did tell them that wasn't the
purpose of a REN and backed up by some universities which had their own
space and the REN seems to have backed off from that position.

:-)  such has to be particularly BAD class. Every Cisco course (ICND, CCNA)
and I'm sure the AFNOG courses teach Routing First and only later teaches
NAT as a way to deal with insufficiency of IPv4 addresses.

Sure they are engineers who never had those fundamentals straight and
somehow ended up running networks - they quickly used NAPT where they
should have routed (because it is quite easy to set up NAT than configure
routing)

The required change from the training perspective is to now say ... "The
sustainable solution to IPv4 insufficiency is IPv6" as well as have a
session teaching the contrary consequences of using NAT.
