ANGLICO traditionally had the static line jump mission to conduct joint operations with Army airborne units for mass parachute insertions. The ANGLICO units may be adding jump billets to their T/O, but I doubt the cash strapped Marine Corps is buying structure to rebuild the ANGLICO paralofts. You can't claim a jump mission without personnel, equipment, safety structure, and training program associated with a paraloft.
The Navy and Marine Corps built our own freefall schools because the Army freefall school could not support our requirements. The Army is not going to open up seats to Marine Corps units without a service validated requirement for training. And money of course. Let's take that a step further. A school without sustainment is a waste of time and money. It's also incredibly dangerous. The Marine Corps would have to purchase the Army's freefall parachute, which I believe is still the MC-4) and train all of our riggers to pack this parachute. Keep in mind that ANGLICO doesn't rate any riggers or a paraloft at this point.
The Air Force already supports the Army Special Forces community with TACPs and CCTs. The Marine Corps doesn't have the money to invest in freefall parachute programs for all of our specialized communities that could use them such as HET, EOD, and ANGLICO. Furthermore, military freefall school does not grant a unit a freefall capability. That takes months of follow on unit training that is frankly beyond an ANGLICO's capability, or requirement, at the moment and would take a significant investment of time, manpower, and money to achieve. ANGLICO's mission is to provide MAGTF commanders with a liaison capability and to plan, coordinate, employ, and conduct terminal control of fires in support of joint, allied, and coalition forces. That does not require a military freefall capabiltiy. In reality, very few special operations missions require parachute insertion. The kinds of missions that do require this kind of off-set infiltration probably exceed the baseline training of the individual ANGLICO attachment. As I mentioned before, the SF already have fully trained organic JTACs, USAF TACPs, and CCTs that already have advanced special operations and specialized insertion capabilities that can support their more sensitive and high risk fire support coordination requirements. If a SOF unit still really wants to jump an ANGLICO Marine into an operation, they can jump them in a tandem parachute system.
