Sure, that falls in the realm of another misunderstood term of "speed work." Again, working within the system you are using it becomes critical to understand the purpose and pace of the workout.
McMillan lays that out for you in his charts with various 600 - 1,600 pace ranges for short and long distance runners and whether it is an interval or sprint workout.
Daniels breaks his out into I and R runs with the I being around 5k pace and R being slightly faster. His I work is rarely over 1,200 except for the 5 minute and under runners. His "ideal" I workbout would be no more than 5 minutes per interval. The R stuff is shorter because of the higher intensity.
Pfitzinger-Douglas lay theirs out as either strides mixed into regular runs or as 5k paced repeats varying from 600 - 1,200.
But none of those things are in the "tempo" range. They are faster and shorter. This is why people will typically respond with the cost of recovery and chance of injury. You are putting a workload on your body that you would normally only do on race day. A very generic rule of thumb is for every mile raced to allow the same number of days for full recovery. If you run 20 minutes at 5k pace, for the average AGer, you are talking basically a 5k. To comfortably recover, you may need up to 3 days in newer runners. Less in more experienced ones. Once a week? Sure, you could do that. But you sacrifice some of your other sessions during the week to do such a thing. Which is why the shorter repeats are prescribed with equal or slightly less than equal recovery bouts between the intervals.
Just some more thoughts .............
