Salesforce lightning support for Marketo Sales Insight

We are using Marketo Sales Insight and planning to enable Salesforce Lightning. I reached out to Marketo support and they mentioned below Sales insight does not below features

Unsupported Features

Marketo doesn't support a few features of Lightning:

•    Bulk email sending - You can't choose a set of leads or contacts and send them an email at one time

•    Bulk adding of leads or contacts to a Marketo campaign at one time

•    The View in Marketo link on leads and contacts

•    The link to the Opportunity Influence Analyzer within opportunities

I want to know, if above features will be available or in road-map in any future release/upgrade?

Do you know of any article/post available with workaround solution for the list of limitation you provide?
