Lucee 6 getMetaData incompatibility

myStruct = { foo:"bar" }
dump(getMetaData(myStruct));

In Lucee 5 (and ACF 2023) getMetaData() always returns a class. In Lucee 6 if the argument is an array or struct getMetaData() returns a struct. For all other data types it appears to still return the class.

In Lucee 5.4, when the argument passed to getmetadata() is an array or struct, it returns the class. However, in Lucee 6.0, it returns a struct.

This change occurred in Lucee 6.0.0.21 and later, as indicated in the commit link: LDEV-2495 - extend function getMetaData and make second argument of L… · lucee/Lucee@4910d4a · GitHub.
This getmetadata() function is related to the issue discussed in the following ticket: LDEV-2495

OK, thanks. Is it not an ACF compatibility issue now though (which is ironic considering the ticket referenced is about achieving ACF compatibility)?

With this code:

<cfdump var="#getMetaData({foo:"bar"})#">

Lucee 6 result:
