IMHO, both interfaces are okay and it is a matter of personal preference. 

Another option is to have a key value option:

draw Text [ font="myfontfamily", style="bold", text="some text" ];

It is relatively simply to define such key-value interface in ConTeXt. For example, see:

https://adityam.github.io/context-blog/post/new-metafun-interface/

Everything is defined in metafun, so it might also work in metapost+metafun as well but I have never tested this outside context.
