cjl from the Sugar Labs committee raised the following concern:

In theory, engagement in the proposal drafting process might allow a
conflicted person to "tip the scales", thereby justifying their
exclusion. However; in practice, it may be that the conflicted
person is the only PLC member with the requisite technical expertise
or situational awareness to draft a suitably detailed proposal. Is
it possible to acknowledge that the rest of the PLC should generally
be capable of taking advantage of the conflicted persons special
knowledge and contributions to the drafting without allowing the
creation of "an uneven playing field".

This change allows the conflicted PLC Person to "disclose material facts
and to respond to questions" to the drafting process, but does not allow
them to do the drafting themselves.
