[web-animations-2] Iteration delay

Greetings to everyone,
I'm curious about the relation of the property discussed in "Proposal for animation-pause property" at https://lists.w3.org/Archives/Public/www-style/2016May/0080.html and its relation to the web animations specification 2 - group of effects and sequence of effects. It seems to me that instead of using groups of effects, its better to have the discussed property and to allow one animation to have more then one effect instead of the one 'target effect'. It does not look nice, to have to define two animations with the same attributes, when there are two effects, at least because of the redundancy. When a group is need, then simply the required effects will be connected to the animation. The sequence of effects could be made by delaying each effect accordingly, hard codding its value, or attaching it to the onfinish event of the previous effect. This could simplify the design of many common animation cases.

No file, test, or implementation entry point is named. Start by reading the linked proposal and the Web Animations specification 2 sections on groups and sequences; completion would require an agreed specification design and scope, which this issue does not define.
