I see the point. However, it does have an impact on the desirability of the future LRT lines.
Eglinton is an odd duck, with so much of it running underground / elevated. The operational expenses will be much higher than for any surface line (and the benefits higher as well, but one can debate whether the benefits justify the costs). In any case, Eglinton is not to be compared to any other line.
But Finch? A very typical line, running almost entirely in the street median. The press release mentioned Finch for a possible delay, too.
If the operation of Finch LRT might have to be delayed due to the cost concerns, that definitely affects future LRT plans, and not in a good way.
