If we had said "for four years, or shorter if we feel like it", *that* would have been a non-guarantee... ... but it's not what's being proposed. What's being proposed is to promise support for the *longer* of (four years) and (until the after- next LTS release), so in particular, it means that a 1.x LTS release will be supported for four years from the moment it's GA'd, period. It might be supported for more than four years, but not for less. Seems like a guarantee to me.
