I'd say as early as possible.
Not sure about Thomas' use case.
I expect most of the extra tables are needed before ACPICA gets
initialized otherwise it could have been specified to put the info
into DSDT/SSDT via ASL.
Sooner or later people will hit the "I need it earlier" limit and
patch:
ACPICA: Introduce new acpi_os_physical_table_add OS callback
shows that it can be done early and that it integrates nicely
with only some additional lines.
