Initially I too thought the email alerts of plugin files changes were too frequent, but now am grateful for a couple of reasons.
One is the notice a plugin might be in need of updates and I'm currently waiting for a few to get up to speed and fix issues before I can fully activated them.
And second, I would not have known that MailPoet (WYSIJA) hadn't properly removed all its files when I had deleted the plugin. *grrrr* Not happy with the discovery of these files sitting in the server. But WF had sent an alert about some file change and mystified, then discovered the residual junk. (It is possible it was my error in my hast to remove the plugin because of the recent hacks to MailPoet and didn't click the right buttons, but still, WF came through.)
------
Note, there is the possibility of a plugin being updated before checking WF notices. The alerts might still be there even after you have fixed/updated the plugins, and therefore it will look like a false call.
Thanks WF.
