Looks good, but need to sort the IPR thingy :)

@shubhamg13 - can you join the WebPerfWG?

@shubhamg13 - can you join the WebPerfWG?

My company is not yet participating in WebPerfWG (or any WG)?

[yoavweiss]

@caribouW3 - can you help? Can we take a one time IPR commitment here?

[caribouW3]

@shubhamg13 's company is a W3C member organization, so the AC rep should make the commitment using the WG's join form. A non-member licensing form will not work.

Can this be accepted if I mark this as non-substantive?

[w3cbot]

shubhamg13 marked as non substantive for IPR from ash-nazg.

[noamr]

Not sure if we can qualify this as non substantive.

https://www.w3.org/policies/process/#substantive-change
"Changes which resolve ambiguities in the specification are considered to change (by clarification) the implementation requirements."
In other words, if the implementation needs changes, even subtle, it is substantive.

Hmm, can this be tweaked?

1. If this has Co-Author, and
2. Co-Author has IPR rights.
