Why is there a difference in syntax between typing buffers and typing files?

For files enclosure in {} for buffers in [], for files optional parameters, for buffers not.

Is it possible to make the syntax of these two the same, because their usage parallels each other?

Example code:

\startbuffer[test]

content of buffer

\stopbuffer

\starttext

\typebuffer[test]

\typefile[style=\ttx]{test.txt}

\stoptext
