Cool End of CF-2 Oils used in 2-strokes

I was browsing the web looking at lubricating oils information and ran across this unexpected letter issued by API noting the end of certifying CF-2 oils. That is the designation, if I understand correctly that DD required for oils it approves for 2 strokes.

The letter suggests other certifications that are able to be used instead. Does this open us for using multigrades year around?

Here is an excerpt from the letter dated July this year. The whole letter is here: http://www.api.org/certifications/en.../new/index.cfm

specification. API’s action to cease CF-2 licensing became necessary after the ASTM Heavy Duty Engine Oil Classification Panel (HDEOCP) notified API that one of the engine tests used to document CF-2 performance, the 6V92TA test, is no longer available.
How this action by API affects current and potential API licensees depends on the claims now made by the licensees and those that potential licensees might wish to make. Currently-licensed API CF-2 products will need to be either upgraded to a more recent diesel engine oil service category (for example, CH-4, CI-4, or CJ-4) or removed from the license. Specific information on how API’s decision will affect licenses is provided below:
After February 1, 2010, oil marketers will not be permitted to use CF-2 inside the API Service Symbol "Donut." Oils that only claim to meet API CF-2 will be removed from licenses on February 1.
API has ceased licensing new oils against the CF-2 specification.
Oils that include CF-2 as one of a series of engine oil categories claimed (for example, API CF, CF-2/SJ) will remain on the license after February 1, minus the CF-2 claim.
