That really depends. For example, Gecko's property storage is optimized 
for low memory use and speed of certain access patterns.  Properties 
aren't stored as strings, but as packed parsed values (effectively a 
"compiled" format).  Not only that but they're identified by numeric 
identifiers (again as a performance optimization; this allows looking up 
information about them via array indexing).

It's not quite obvious to me how to sanely store unrecognized properties 
in this setup, and it would certainly require a good bit of reworking of 
the current code and data structures.
