4279. §[fs.op.absolute] Non-normative encouragement should be Recommended practice

Discussion:

[fs.op.absolute] has a note giving strong encouragement, which should be normative:

[Note 3: Implementations are strongly encouraged to not query secondary storage, and not consider !exists(p) an error. — end note]

The part about !exists(p) not being an error could definitely be a Recommended practice paragraph. Referring to "secondary storage" might need to be phrased differently to be normative (maybe with a note clarifying that the normative wording is referring to "secondary storage").

Proposed resolution:
