If {sei}-clause could enclose a sentence, the grammar would be 23 bytes smaller. If we add {soi}-clause to "free", the structure and the usage will be very similar to {sei}-clause. If we had the structure of "SOI sentence SEhU" from the beginning of Lojban, I would have never used "SEI terms selbri SEhU".
Similarly, you can eliminate LE and move it to LOhOI saving even more rules.
