This will make the E-RAB lookup more complicated for... what kind of robustness? When doing the lookup with partial knowledge of the key (`erab_uid()`), you can no longer use `dict:find` or `dict:get`, you'll have to convert the dictionary to a list and recursively check each item. This is significantly slower.
The only scenario I could think of is the `PATCH SWITCH` procedure, when it's the eNB establishing E-RAB (not the MME as usual). In that case the `PATH SWITCH REQUEST` contains only the `eNB-UE-S1AP-ID` alone. We do not implement this procedure yet, and implementing it would require quite a lot of additional changes.
