not a problem, maybe note for documentation

From theDGL docs

"DGL can use either 32- or 64-bit integers to store the node and edge IDs. The data types for the node and edge IDs should be the same. By using 64 bits, DGL can handle graphs with up to 2^64 -1 nodes or edges. However, if a graph contains less than 2^32-1 nodes or edges, one should use 32-bit integers as it leads to better speed and requires less memory. "

for our purposes, I believe 32 is sufficient, I assume that is what we are using...
On second thought, I will check and put an if case in for initial size plus max additions.
Still could use documentation.
