FHIR Package Loading Sadness

Im playing whack a mole importing an IG (which is a fairly typical exercise with fhir packages) through FHIR packages, and getting at some parts I cant seem to work around with some store errors...

Im getting MAXSTRING on `hl7.terminology.r4`:

Saving hl7.terminology.r4@3.1.0
Load Resources: hl7.terminology.r4@3.1.0
Resource Used in Multiple Packages:|20100826(hl7.fhir.r4.core@4.0.1,hl7.terminology.r4@3.1.0)

  Set sc=rsrc.%Save() Throw:('sc) ##class(%Exception.StatusException).ThrowIfInt
<THROW>zaddPackageResources+74^HS.FHIRMeta.Load.NpmLoader.1 *%Exception.SystemException <MAXSTRING>  %SaveData+28^HS.FHIRMeta.Storage.Rsrc.1

For this one, I started by declaring a ridiculous "99999999999999999" for MAXLEN on the properties of HS.FHIRMeta.Storage.Rsrc, then removing it altogether and get passed it... no dice.

and STRINGSTACK for `us.nlm.vsac`

Saving us.nlm.vsac@0.3.0
Load Resources: us.nlm.vsac@0.3.0

   set rsrc.json = json.%ToJSON()

I have no ideas on this one, but thinking it may be a symptom of the first one.

Set tSC = ##class(HS.FHIRMeta.Load.NpmLoader).importPackages($lb("/usr/lib/node_modules/hl7.terminology.r4"))

If you had to hack the system classes to get this to work, which approach would you take ?

These packages are fairly common I would think, so I think a back end limitation has been introduced.
