anything "can" be ported once mozilla creates a API, even TreeStyle
The point is there is no API to do it today, and unlike the dev I do not believe the new API;s will be in 57, I see no evidence to support such a claim.
Further if you continue to read on the issue, you see the developer has clearly said this is an expermint that will never be mainlined and development will likely stop
"Having said all that, it's likely that at some point in the future, TabCenter will no longer be developed, and at that point, we'll recommend people switch to one of the other side-tabs add-ons."
he continues
"TabCenter isn't something that will live forever."
So no TabCenter is not a replacement for TreeStyle, and never will be
