Yes, but I think FDev were left with little choice when it came to exploration tools. Given how many committed explorers were/may have been engaged in long term exploration when sweeping technological changes magically manifest across the known galaxy, the only other option for the FSS was to ensure it weighed and drew the same power at the lowest point of any possible existing DS to ensure carefully crafted builds didn't implode. Doing what they did was probably the easiest, and opened up a valuable slot for small/med exploration ships. Opening the FSS up to engineering could rebalance the lack of outfitting choices.
I think FDev should have bitten the bullet on the 'explorers being out in the black' issue. If they'd announced that there would be significant changes a month in advance and given players the option of a one-time teleport back to their starting system they'd have been able to be a lot more creative in how they approached the new exploration.
Given that the FSS currently does everything and has infinite range, I'm not sure how engineering options could be retrofitted in.
