On the third ballot[1], #117 (Real numbers have imaginary part #e0)
resulted in a strong 6:2 win for "exact-only", and this decision was
implemented in R7RS-draft-3, and carried forward in drafts 4-6.

However, this change was reverted in R7RS-draft-7.  The ticket[2] states
"This decision was reversed because it created a silent incompatibility
with R5RS", but the compatibility issues were obviously known to the WG
at the time of the third ballot (three out of five rationales explicitly
mentioned compatibility), and yet "exact-only" still won 6 out of 8
votes.

How can such a strong win for "exact-only" be reversed by the editors,
and why wasn't this reversal brought up on the mailing list?
