It looks like they still have to tippy-toe around SATCOM. At IDEAS 2018, SUPARCO told me that PAKSAT-MM1 will continue using Ku-band, instead of Ka-band (which other militaries are moving to with their comms satellites). There are also no immediate plans for X-band.
To me it seems that we're actually having trouble accessing Ka-band and X-band, at least for now. The military utility of those frequencies isn't lost on anyone, certainly not the US. Of course, they'll need to keep replacing satellites every 7-10 years, so it could be a cost issue (and something they'll rectify in a future satellite).
