Paging File -- Windows 2012 R2, HyperV host & guest OS ?

Both of the below links act like you should "leave the
Windows 2012 default of system managed pagefile on the
C drive if you do NOT have issues"

Does anyone disagree ?

If so, what is your recommendation ?
===========================================================
https://support.microsoft.com/en-us/kb/2860880 says
For Windows Server 2012 R2 Hyper-V, the page file
of the management OS (commonly called the host OS)
should be left at the default of setting of
"System Managed." This is per the Hyper-V
product group.

http://windowsitpro.com/hyper-v/hyper-v-pagefile-configuration says
Windows Server 2012 changed this; the system managed
pagefile is intelligent and by default will ensure
that the pagefile is at least big enough to capture
a kernel memory dump but isn't the size of the
complete memory. If the system experiences a bug
check (blue screen), then for the next four weeks
the pagefile will be increased in size to match
the amount of memory. This ensures that if a bug
check occurs again, the entire contents of memory
can be captured; after the four weeks has passed
(the date of the last bug check is stored in the
registry value HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet
\Control\CrashControl\LastCrashTime), the pagefile will
shrink back to the smaller size. Jeff Hughes documents
this in the blog post "Windows 8 and Windows Server
2012: Automatic Memory Dump."

I agree with the statements made in the opening post.

System Managed. and the default location is generally fine, as it's not defragmented, but read the EE post below.

This was discussed here, in another question I answered.
