After LU04470 and LU04469 have been applied, must the CICS Regions be recycled?

Issue/Introduction
Applying maintenance, in production this coming weekend.
In particular PTFs: LU04470 and LU04469,which update certain IDMS CICS-related modules
with assemblies that use supported CICS libraries.
My question is should all the CICS regions also come down when I swap out the load library and IDMS is down?
Environment
Release : 19.0
Component : IDMS/DB
Resolution
LU04470 and LU04469 were a reassembly of IDMS CICS-related modules using a more current CICS macro library. No functionality was changed. However, a change to a CICS macro (DFHRMCAL) made a hard-coded displacement in the custom #UCFCICS no longer correct.
There is no real need to cycle a CICS region if you swap libraries in the CICS JCL to libraries containing this maintenance. If you do bring up a CICS region with libraries
that have LU04470 and LU04469 applied, it's important that the newer version of the #UCFCICS (with the updated hard-coded displacement) is used.
Important Note:
As a general rule, when you apply PTFs the target CAGJLOAD gets updated with all updated modules.
Then to implement the PTFs, either the entire loadlib or just the updated modules must be copied to the CAGJLOAD equivalent in CDMSLIB and CV must be recycled to bring in the updated modules.
AND if you have CAGJJ01 FMID and use CICS to access IDMS the same must be done to the CAGJLOAD equivalent
in the CICS startup DFHRPL concatenation if any FMID CAGJJ01 modules were updated by the PTFs applied.
It is recommended that the CICS regions be recycled to bring in the updated modules
