Are the icons up to date? Missing icons such as ms-Icon--MSNVideos

Are the icons upto date? Not seeing the ms-Icon--MSNVideos icon for example.

No the CSS is not up to date for new icons... but the fonts are since the library gets them from Office Fabric CDN. I suggest you use some CSS to get the icons you want, like this:
<style lang="scss"> .ms-Icon--PageLock::before { content: "\F43F"; } </style>
