Yes, the plan is to migrate all use of /deep/ and ::shadow in Polymer elements to custom properties, as it has been removed from the spec and as noted Chrome has posted deprecation warnings. The vast majority of that migration was already done during the 1.0 port and anything remaining should be vestigial at this point and should be cleaned up soon. I opened an issue for paper-slider; feel free to open issue on any other stragglers you find (a quick search didn't find any).
It is unlikely that Chrome will actually remove support for these combinators in the immediate future and the Shady DOM styling shim does support it for now so there is no immediate risk of breakage; however our team rule is to not rely on them going forward, and users obviously shouldn't either.
