Bug. It's trying to auto-identify an EPSG code for you when it writes the tile index. Please file a bug to change this to write compound WKT.

This should maybe be the default behavior anyway for readers.tindex. The SRS column in the tile index is a convenience for upstream users of the tile index files themselves, not for PDAL. It would be one way to do some kind of default/override scenario, but that is not as common as do the expected thing of reading the SRS from the files. Please file a ticket on this one too.
