Nevertheless it's difficult to handle in cases where you just need some information about a certain IMSI. That is why it is done differently in GSUP where the complexity of MAP can be handled by a separate proxy, and there is no such a size restriction.
Please note that I had extended GSUP to also handle the separate/nested LU + ISD transactions, at least in the SGSN as far as I remember. So the subscriber related data can either be inside the LU-response or in the seperate/nested ISD-request.
