Why does filedAgainst exclude archived values in allowedValues, while priority and severity include them?

In RTC (EWM),  a difference in how archived lookup values are handled in the allowedValues list returned by the OSLC resource shape API:

• For rtc_cm:filedAgainst (category field of type rtc_cm:Team ), if a category is archived, it is excluded from the list of allowed values.

• However, for oslc_cmx:priority and oslc_cmx:severity (both of type rtc_cm:Literal ), the archived values still appear in the allowedValues list.

Can you please explain why there is this difference in behavior?

Why are archived enumeration values (like priority/severity) included, while archived categories (filedAgainst) are filtered out from the API response?

Understanding the rationale behind this inconsistency would help in aligning our integration logic with RTC's intended design.

Thank you
