As well as via apar PH09898 on previous CICS TS V5 releases, this RFE is satisfied by CICS Transaction Server for z/OS V5.6 which is Generally Available today 12th June 2020. The security check parameter SURROGCHK has been removed from DFHXCOPT. It was introduced in CICS TS 1.1 as a migration aid from CICS ESA 4.1.0 as there was a change in behaviour.
EXCI will now always perform a surrogate security check.
This RFE is also satisfied by CICS Transaction Server for z/OS V5.6 which is announced today 7th April 2020 and which has a planned availability date of 12th June 2020.

This RFE has been addressed via apar PH09898 on CICS TS V5 releases. The security check parameter SURROGCHK has been removed from DFHXCOPT. It was introduced in CICS TS 1.1 as a migration aid from CICS ESA 4.1.0 as there was a change in behaviour.
EXCI will now always perform a surrogate security check. If you still need the ability to specify SURROGCHK=NO then you will need to request a usermod from IBM support.
Due to processing by IBM, this request was reassigned to have the following updated attributes:
Brand - Servers and Systems Software
Product family - Transaction Processing
Product - CICS Transaction Server
For recording keeping, the previous attributes were:
Brand - WebSphere
Product family - Transaction Processing
Product - CICS Transaction Server
Thank you for your detailed description of the use case.
As this is a very specific configuration, I think that your suggestion about an enhancement to QUERY SECURITY would be the best way to implement the requirement.
This is something we would like to address in a future release.
