I object: I proposed that you use a custom EPSG code >32767, as 
recommended by EPSG. Please refer to my email, included below.

EPSG code: EPSG:0

-1 from me, because EPSG:0 is already reserved by the EPSG OGP Geodesy
Subcommittee. Would you consider another integer >32767? Think of other
extensions, like 900913. What is l33t for c4rt3514n (still missing a few
digits)?

Furthermore, if we were to accept EPSG:0, would GeoServer start
advertising it in its Capabilities?

Kind regards,
Ben.

EPSG Codes

The OGP Geodesy Subcommittee has reserved the integer range 0 to 32767
for use as codes. As of dataset version 6.3, the integer range from
6,000,000 to 6,999,999 was also reserved for codes for geographic CRSs
in explicitly described degree representations, but this is no longer
supported. To prevent conflict with future additions to the EPSG
dataset, users who wish to augment the data with their own information
should utilise codes greater than 32768.

If users wish to supplement the change table with their own entries, it
is important that the user's change notice IDs be above the EPSG integer
code limit of 32,767.0. Such an entry in the change table is required
for users to deprecate any erroneous user data.
