Ja. And to those who say it's more work for Bitmain's coders so Bitmain won't do it: Um, they just changed from using the Xilinx SOC to using one from Altera - pretty safe bet that the hardware change required significant re-coding of at a minimum the FPGA portion of it. Since the Cyclone-V still uses the same ARM-9 CPU as the Xilinx SOC did at least that bit would be mostly the same.
Implementing Eco modes is nothing compared to that

Maybe, but their target market is the "from new, stick it in a rack until it dies" people. They don't care about hobby miners too much, since that's not where their profit is (R4 excluded).
I find it quite interesting that they don't in fact appear to do any per-chip or per-board even tuning per-boot - it's just making sure that each board is as-shipped from factory, setting the ASIC speeds and expected core count, then trying all the boards.
There is no variance in the picked speeds at all, as far as I can see - it just validates that everything is within expected ranges.
When you do a new 'apply settings', it does some additional checks, but again, none of these appear to change the hashrate significantly.
