The normal way to load a new font from a external typescript is

\usetypescriptfile[<name>]
\usetypescript[<name>]
\setupbofyfont[<name>]

In MkII you don’t need \usetypescriptfile to load the default fonts (times,
palatino etc.) because context loads them when it generates the format
but MkIV loads them the fonts are used to save memory.

Because in many cases the name of the file is the same (with a “type-” prefix)
as the font context tries to load the file itself when you enable the font with
\setupbodyfont, even the \usetypescript call (the second argument isn’t needed
because we aren’t restricted to 256 anymore with LuaTeX) isn’t necessary
because this is also done by \setupbodyfont.

You can do this. It’s always better to make the setup of the document before
\starttext, startcomponent etc. because some values are set/reset with \starttext.

The only things which are posted on the developer list nowadays are bug reports
with possible fixes or extensions to the context programing language.
