Conversion is made quite easy (compared to other systems
I am familar with) because the blocks are tagged with their type
(data, SHA1 hashes of data, SHA1 hashes of hashes of data)
and the block tree is a standardized format used by all clients,
so conversion can happen independent of the program that wrote
the data.  After converting the data, all the clients and the server
would have to be rebuilt with the new hash function.

It is not necessary to write a separate program to convert fossil
data, vac data, etc.

Some day it will be necessary to worry about this.  It is not today.
