I've looked briefly at the materials synthesis (first part of their Supplementary Materials section). I agree with you, the synthesis is trivial. The 10e-5 vacuum is easily reached with a turbopump backed by a mechanical pump, nothing exotic or expensive.

indeed, and i wonder if you could elide the vacuum entirely with a noble gas (presuming the vacuum is required to avoid reactions with atmospheric gases)

Could be, and good idea.
If they're processing in a vacuum to avoid N2 and/or O2 and/or H2O chemistry, then a dry inert gas might be useful.
Heating above 100°C to drive off H2O, followed by a purge with dry Ar might give the desired result without needing a vacuum system.
