[TLS] Comments on TLS extension mechanism

["Kyle Hamilton" <[e-mail]>]

I would like to request that a specific TLS extension number, say
65534, be used as a means of negotiating arbitrary TLS extensions for
specific application and research purposes, with the express
understanding that this mechanism SHOULD NOT be used unless no other
option presents itself, AND the implementor is aware of any potential
security issues that may be introduced.  The format I propose would be
akin to:

struct {
   int extension_ID,
   OID arbitrary_extension,
   int extension_data_length(65535)
   opaque(arbitrary_extension_data)
} TlsArbitraryExtensionType;

Since section 5 of RFC4366 (and predecessors) states that new
extensions shall ONLY be approved through RFCs approved by the IESG,
this is the only logical place to propose such that I can find.  If
this is not the appropriate forum, please let me know.
