I noted that in the later sentences of my comment. Yes, the platform is larger. But in some cases, it's also more sensible now that standardization has had 20 years to work it over. When Gecko was being developed, it was half implementing standards and half reverse engineering Microsoft's undocumented web APIs. Still, I'm sure it's nevertheless harder today and that's why I said so near the end of my comment.
