I gather that the UK CAA is entering 'CB IR' as the licence endorsement....
If that is the case then it is just another example of the inability of the CAA to understand the regulations, like adding class ratings to an LAPL (or a B737 rating to a CPL(H)!). It is symptomatic of the current , inept management and their drive to cut costs. If you pay peanuts, guess what happens.
