1. Is it true that 1-sided edge can be tolerant? Say, we had a tolerant 2-sided edge, then one of the adjacent faces was deleted or unhooked - the edge becomes one-sided tolerant edge.
If the answer to the question 1 is yes, the the second question is:
2. What's the good practice - does it make sense to have a 1-sided tolerant edge, or it is better to "detolerize" it (for stability of downstream operations) ?

Tolerant 1-sided edges are possible. In the case you mentioned (unhooking one face incident to a TEDGE) and in some other cases. The TEDGE tolerance is defined by the gap between the 3D curve under the EDGE and the PCURVE. If you construct a face where some of the boundary edges do not lie within SPAresabs of the surface, it will be a TEDGE. I don't think you need to modify TEDGEs manually though, with one exception. If you have a edge where the incident faces intersect sharply, api_lop_tigthen_gaps can be used to create a new edge geometry by intersecting the neighboring surfaces. In principal, sharp edges shouldn't need to be TEDGEs, because ACIS can intersect the surfaces for you.
