No, it is very easy, it just takes up some of your time :-)

If you follow that, it will replace your already installed samba files 
and an update to these could again replace your samba files.

You seem to be correct, Ubuntu doesn't seem to have noticed that 4.4.3 
is in debian sid and I thought Ubuntu was based on sid.

Your best plan would be to just:

sudo apt-get install acl attr autoconf bison build-essential \
debhelper dnsutils docbook-xml docbook-xsl flex gdb krb5-user \
libacl1-dev libaio-dev libattr1-dev libblkid-dev libbsd-dev \
libcap-dev libcups2-dev libgnutls28-dev libjson-perl \
libldap2-dev libncurses5-dev libpam0g-dev libparse-yapp-perl \
libpopt-dev libreadline-dev perl perl-modules pkg-config \
python-all-dev python-dev python-dnspython python-crypto \
xsltproc zlib1g-dev

As a normal user:

cd /usr/src
wget https://download.samba.org/pub/samba/stable/samba-4.4.3.tar.gz
tar zxf samba-4.4.3.tar.gz
./configure
make
sudo make install

This will install Samba into /usr/local/samba and you will now need to 
alter $Path so that /usr/local/samba gets searched first:

echo "PATH=/usr/local/samba/bin:/usr/local/samba/sbin:\$PATH" > 
/etc/profile.d/samba4.sh
export PATH=/usr/local/samba/bin:/usr/local/samba/sbin:$PATH

Now create a domain member smb.conf in /usr/local/samba/etc
Alter the paths in the Samba init files to start the smbd, nmbd and 
winbindd binaries in /usr/local/samba/sbin instead of the ones in /usr/sbin

Start Samba
