it all depends on how they implement it but for a feature rich opentype 
font extend will not work out well unless on also scales up the internal 
font properties (and i'm not sure if that would work out well with for 
instance cursive features)

anyhow, as it's probably uses for a rare cases you can try

\setupbodyfont[dejavu]

\defineeffect [thicker] [alternative=both,rulethickness=0.3pt]

\starttext
     test \starteffect[thicker]test\stopeffect
\stoptext

these pseudo slant and bold definition tricks are an inheritance from 
pdftex and therefore in luatex ... we'd never introduced them otherwise 
as one should use proper bold fonts (or nothing)
