<p>I was just rereading the SegWit benefits page and noticed that the section <a href="https://bitcoincore.org/en/2016/01/26/segwit-benefits/#moving-towards-a-single-combined-block-limit" rel="nofollow noreferrer">Moving towards a single combined block limit</a> contains an example in which sigops count towards the blockweight.</p>

<p>Did this become part of the final version of SegWit? If not, what happened to this idea?</p>

I was just rereading the SegWit benefits page and noticed that the section [Moving towards a single combined block limit](https://bitcoincore.org/en/2016/01/26/segwit-benefits/#moving-towards-a-single-combined-block-limit) contains an example in which sigops count towards the blockweight.

Did this become part of the final version of SegWit? If not, what happened to this idea?
