The deprecation of v2 was just announced in the Cast Dev Google+ community: https://plus.google.com/+LeonNicholls/posts/bgR15tDibTn
I imagine if not fixed, the effects might range from features not working to Chrome crashing when using the removed SDK methods to not compiling whenever the client library is updated.
Forgot to put the bug number in the CL:
[Clank MR] Remove v2 code for MediaRouter and MediaFling
The v2 code is planned for removal in M74. This CL removes
all the v2 code on the Java side.
Here are the dex and APK size changes in this removal
compared with the migrated code (in parenthesis).
Dex:
-284 (vs. +100) entries fields
-680 (vs. +292) entries methods
-97 (vs. +49) entries types
-241 (vs. +69) entries strings
Dex file size: -70,38KB (vs. +31.35KB)
Apk size: -36.72KB (vs. +12.88KB)
