I do not think it would be a concern for 64 bit sql instance. Correct me if I am wrong.
Hi, thanks for your question.
It is certainly not as large a concern however, it should be noted that you can still run out of VAS even on 64-bit if you run low on physical memory. This is why it is recommended that you configure the Maximum Server Memory Setting explicitly in SQL Server.
I hope this answers your question.
