normally typescripts like that end up in tex/context/third (maybe at 
some point we can collect extra typescripts in one package)

a few suggestions:

\definefontfeature[slanted][default][mode=base,slant=.25]

best define "roboto-slanted" as you don't want to overload other 
definitions of slanted and this is rather font specific .. and are you 
sure you want base mode here?

\definefontfeature[roboto-slanted][slant=.25]

\definefontsynonym [\s!SerifItalic] [\s!Serif] 
[\s!features={default,roboto-slanted}]

should also work and delays default

also, name type typescript type-imp-roboto.tex (or .mkiv)
