SPARQL has nothing to do with this - your survey needs to test parsers and the handling of such data end-to-end. Equality of constants is only part of the picture.  Try `xsd:decimal("2E3")` rather than the `^^` form.

Your survey is needs to cover RDF/XML. A system that uses an existing validating XML parser needs changing as well.

SPARQL was not my point. It is a legal cast in F&O - a non-RDF standard with a significant adoption.
SPARQL queries would require the cast for stability across remote stores.

> We could fix this by either changing JSON-LD, or changing `xsd:decimal`. The 2nd option seems more reasonable to me, all the more that many implementations are already supporting E-notations.

It's a SHACL change.
