A simple algorithm with assume that everything following the dot is the

it's not that complicated ... say that you patch this way:
function schemes.cleanname(specification)
return (gsub(specification.original,"[^%a%d%.]+","-"))
end
local function fetch(specification)
local original = specification.original
local scheme = specification.scheme
local cleanname = schemes.cleanname(specification)
that will be the current method. Now you can experiment with:
Can cleanname be passed as a parameter of the specification? Then we can
have
local cleanname = specification.cleanname or
schemes.cleanname(specification)
This way, I can only change the cleanname of the files that are
downloaded by my module without affecting the cleanname for any other
command that might want to download a file.
I made this ... as this is rather specialized tuning (that might confuse
users) it's a directive:
\starttext
\enabletrackers [resolvers.schemes]
\enabledirectives[schemes.cleanmethod=md5]

\stoptext
currently 'strip' is default but we can decide on md5
