buffer~ and float64

hi
buffer~ reference says: The word format followed by a number or a symbol will set the bit-depth or sample-type of the buffer.

but trying to set the format to "float64" doesn't allow me to store 64-bit floats in the buffer. as far as i can see, this serves merely as export format, if you write the buffer contents to disk.

this renders the float64 setting pretty useless in my opinion.

as far as i can think back, internally buffer~ has always been storing 32-bit floats. are there any plans to change this?

thanks,
volker.
