Hi,
The only solution other than Dead Ma= n's Switch to avoid gradual loss Bitcoins in transaction is increasing = the divisibiliy of Bitcoins. Then Bitcoin values will need integer of more = than 64 bits. Could that be done with soft fork?

You can implement this = already, but only for ~1 year expirations.

IF <normal script> ELSE <1 year> CHECKSEQUENCEVERIFY ENDIF

Perhaps it would make sense to propose a flag extending the range of relati= ve
lock-times so you can do several years?
