Requiring PROJ 6 or newer for MapServer 8.0 sounds reasonable. It is
already required for pyproj 2, libgeotiff 1.5, and the upcoming GDAL 2.5.

7.4 and 7.6 should ideally support PROJ <= 6, with 6.x supported by
defining ACCEPT_USE_OF_DEPRECATED_PROJ_API_H, like QGIS does. The next
MapServer release should also move away from using projects.h in PHP
MapScript.

Because it will take significant time to get all projects to support
PROJ 6 (it's removal of projects.h and
ACCEPT_USE_OF_DEPRECATED_PROJ_API_H requirement for proj_api.h), PROJ 6
is unlikely to land in distributions any time soon along with all
projects that require PROJ 6 or later.

Kind Regards,

Bas
