Yes there are: multipart forms send more data since every field has its own MIME header. From RFC2388: "The multipart/form-data encoding has a high overhead and performance impact if there are many fields with short values. However, in practice, for the forms in use, for example, in HTML, the average overhead is not significant." If this overhead was deemed not significant in August 1998, in my opinion it is even less significant now and this is a change we could make without any problems.
