Removing query parameters on resource files

In a Plone site we are developing, collective.js.jqueryui resources (js and css) are being requested with a query parameter:

https://www.mysite.domain/collective.js.jqueryui.custom.min.js?version=None

Varnish does not cache requests with query parameters. Is it safe to remove the above query parameter? What are the potential negative implications, if any, if we remove it? I have checked that the files returned with or without the query parameter are the same.
