That is a good point, and is another reason why I don't want to use an
arbitrary interval such as [0..1] and instead a concrete value such as
seconds or milliseconds. LMMS considers the x100 button as part of the
model, but really, to me: this is a presentation issue. The model (the
actual envelope and LFO implementation) should just take a value in seconds
and roll with it. The x100 selector is really just a convenience to make
the knob's accuracy more closely represent the range that the user wishes
to work in. So really, the maximum time of an envelope segment, or the
period of an LFO need not be limited, (except maybe the lower bound by the
nyquist frequency). Perhaps a more intelligent knob widget could allow the
user to right click and specify the range they wish to tweak.
Any thoughts on an appropriate human interface?

Nope. The "tempo-sync" feature allows the user to specify a value in beats,
but this is ultimately converted to seconds before reaching the area of
code that I am currently discussing. I don't even want to think about
tempo-sync at this point. I may have to rely on midi-beat-clock or an
additional LV2 extension to support this. Definitely a version 2.0 thing.
