Comment 1 for bug 1089681

Yes, the limitation of 31 indexes is implied by the current format of .exp files. Currently, an .exp file is always a 16K page divided into 512-byte segments. The first segment contains the number of indexes and the table name. And the remaining 31 segments contain IDs, root page offsets and names for each index in the table.

This should be easy to fix, as I don't see a reason for an .exp file to take just one page.
