app cannot create theme/storefront-accessable metafields

[den232]

The Metafield Definition Catch-22 ...

app cannot create theme/storefront-accessable metafields

For theme access to product metafields, they must have definitions NOT IN app-specific namespace

For storefront access to product metafields, they must have definitions

graphQL can create definitions, 

but in order for the definitions to enable storefront access,

they must be in an app-specific namespace (such as app--1234567890--custom)

Note that the appId number varies for each shop

Thus, it appears to be impossible for an app to create theme-accessable metafields

Any suggestions?  Thanks!  jb
