Much friendlier - this means some custom transforms might just support optional chains out of the box (maybe not wholly correctly, but in some way without crashing).

Relaxing the assertions on
updateCall/updatePropertyAccess/updateElementAccesswhen used with aCallChain/PropertyAccessChain/ElementAccessChainto fix a crash in the TS transform and to improve backwards/forwards compatibility with external consumers of the API.If you call any of the three mentioned
updateXfunctions on anXChainnode, the correspondingupdateXChainfunction is called instead with the current value ofnode.questionDotTokenpassed as thequestionDotTokenargument.Fixes #33744
